From RS PRO, this torque wrench is compatible with 1/4 inch driver bits, and is designed to prevent over-tightening when fastening nuts and bolts. The tool applies a pre-set level of torque before 'breaking', preventing you from potentially applying too much force to a fastener.
This torque wrench works when used either clockwise or anti-clockwise, and is ideal for use in low torque applications.
Torque Setting is Required before Use
1. Engage the 1/4'' square drive into an appropriate Torque Analyser and slowly apply torque in a clockwise direction until the handle 'breaks'. Note the reading.
2. Remove handle from Analyser and using hexagon key provided remove handle end cap.
3. Insert 3mm hexagon key into grub screw in the end of the adjusting screw. Turn grub screw 1/4 turn anti-clockwise to unlock existingtorque setting. Insert black adjusting key into handle of tool andengage adjusting screw. Rotate using 5 mm hexagon key. Turn clockwise to increase or anticlockwise to decrease torque.Do not unscrew beyond 6mm of end of handle. When set correctly, lock torque setting by re-inserting 3mm hexagon key into grub screw and turn clockwise. Do not attempt to adjust torque setting without first releasing the lock.
4.Re-check torque setting.
